【課題を解決するための手段】
この目的は、本発明によれば、請求項１の特徴を有する装置によって達成することができる。 [0005]
[Means for solving the problem ]
This object is achieved according to the invention by means of a device having the features of claim 1.

本発明によると、この装置は、てこ、ばね部材、およびロック装置を含んでいる。てこは、ロック装置により、特定の位置に保つことができる。ばね部材は、ばね部材とてこの間に固定的な結合が形成されるように、または伝動上の結合が生じるように、てこに配置されている。この配置にあっては、てこの回転運動によってばね部材の変形が行われ、このときばね部材の有効となる引張り力が引張り部材に伝達される。 According to the present invention, the device includes a lever, a spring member, and a locking device. The lever can be held in a specific position by the locking device. The spring member is arranged on the lever so that a fixed or transmission connection is formed between the spring member and the lever. In this arrangement, a rotational movement of the lever causes deformation of the spring member, and the effective tension force of the spring member is transmitted to the tension member.

このてこ、および／またはこの別のてこは、胴軸から偏心して配置されたてこ軸を備えていることが好ましい。この別のてこと引張り部材は、好ましくは直線状案内部材を介して互いに連結され、これにより、別のてこと引張り部材との間での相対運動が可能になる。このてこと別のてこは、好ましくは、互いに回転可能に共通のてこ軸上に配置することができる。てこと別のてことの間のばね部材は、このばね部材を介して、てこと別のてことが永続的に伝動可能な状態で連結されるように配置されることが好ましい。ばね部材は、この場合、力を伝達するブリッジ部材として作用する。さらにまた、係合部材を備えることが可能であり、この係合部材は、予め定められた角度状態を介して、互いにてこと別のてこの回転を阻止し、これにより、ばね部材が付勢された状態に保たれるとともに、てこと別のてこが共に回転運動することを可能にする。本発明のこの実施態様にあっては、これらのてこ間の角度は、第１の回転方向において引張り方向に抗した回転の場合には一定に保たれ、また、第２の回転方向においては実質的に一定に保たれる。ブリッジ部材として作用するばね部材により、てこが永続的な伝動状態に連結されている場合も、そしてまた、係合部材により付勢状態に保たれているばね部材を介して、これらのてこが連結されている場合も、てこと別のてこは、恒常的に作用連結状態にある。さらにまた、てこと別のてこの間におけるばね部材は、力を伝達するブリッジ部材として作用するこのばね部材を介して、てこと別のてこが互いに連結可能となるように配することもできる。上述したような、てこおよび／または引張り部材と連結可能なばね部材は、付勢された状態に保つこともできる。このようにして、例えば、ガス圧ばねに似た、ケーシング内のコイルばねを、ガス状媒体の代わりとして、付勢された状態に保つことができる。弓形状の案内部材、特に、胴軸から同心的に延び引張り部材を案内する案内面を有するつなぎリンク案内部材を備えるようにすることも可能である。さらにまた、引張り部材に取り付けられ、弓形状案内部材内を、そしてまた直線状案内部材内を案内されるようになっているスライド部材を備えるようにすることが可能である。本発明のさらに他の実施態様にあっては、伝導機構として（特に、固定ブロック、移動ブロック、スピンドルからなるねじ伝動装置として）構成されたロック装置を備えることも可能である。このロック装置は、ロックされたてこを、引張り方向に相応する第２の回転方向に動かすことができるような回転状態において、引張り方向に抗する第１の回転方向に、てこをロックする。
Preferably, the lever and/or the further lever have a lever shaft arranged eccentrically from the barrel shaft. The further lever and the tensioning member are preferably connected to each other via a linear guide member, thereby allowing relative movement between the further lever and the tensioning member. The lever and the further lever can preferably be arranged on a common lever shaft so as to be rotatable relative to each other. A spring element between the lever and the further lever is preferably arranged so that the lever and the further lever are permanently connected in a transmission-enabled manner via the spring element. In this case, the spring element acts as a bridge element for transmitting force. Furthermore, an engaging element can be provided, which prevents the lever and the further lever from rotating relative to each other through a predetermined angular position, thereby maintaining the spring element in a biased state and allowing the lever and the further lever to rotate together. In this embodiment of the invention, the angle between the levers remains constant when rotating against the tensioning direction in a first rotational direction and remains substantially constant in a second rotational direction. The levers are permanently coupled to each other whether they are permanently coupled by a spring element acting as a bridge element or via a spring element held in a biased state by an engaging element. Furthermore, the spring element between the levers can be arranged so that the levers can be coupled to each other via the spring element acting as a force-transmitting bridge element. The spring element connectable to the lever and/or tension element, as described above, can also be held in a biased state. In this way, for example, a coil spring in a casing, similar to a gas pressure spring, can be held in a biased state instead of a gaseous medium. It is also possible to provide an arcuate guide element, in particular a tethered guide element extending concentrically from the barrel and having a guide surface for guiding the tension element. It is also possible to provide a slide element attached to the tension element and guided in the arcuate guide element and also in the linear guide element. In a further embodiment of the invention, a locking device configured as a transmission mechanism (in particular as a screw drive consisting of a fixed block, a moving block and a spindle) can be provided, which locks the lever in a first rotational direction opposite to the pulling direction in a rotational state in which the locked lever can be moved in a second rotational direction corresponding to the pulling direction.
